Rotary Engine no good lah

[aiM]

errr.. rotary engine also can produce FIRE at the exhaust! broom broom!!

 

[endless551]

Which workshop rebuilt the engine? Just curious coz if good job then good info for others in Penang that view this forum to check out next time they need engine.

errr... good job? Be a direct straight to the point not beating around the bush Msian Ah-beng.. Rebuilt engine still smoking!?!? 2t oil?? :D

 

[phat7]

when i was in penang there was nobody that could rebuild rotary. but that was way back in 2000-2003

 

[alex_77]

i also dono where is the engine rebuited...my fren chop shop get it for me ,if i'm not misstaken he take from M-POWER chop shop in kl.u guy know this chop shop?? ...dono lah ,,he say this is rebuit in japan....but 1 thing i can sure is the o-ring in flywheel there is new and the engine inlet outlet look very clean,between the rotor housing also got silicon gum (the gum can see is the new 1).can look this engine had been open lah...i also not very pro in rotery engine,soo need some sifu to teach me loh...

A fren of mind was thinkin of gettin an FD auto as she just loves the curvaceous shape. However, i've observed that she travels quite a bit and 1 can only expect her current honda jazz 1.5Dsi to be rather frugal with the fuel consumption. I'd like to hear from you guys what your average fuel consumption is? ie how much per full tank n how many ks you get to run b4 filling her up again. thanks

No comparison

our FDs are 1.3L so very good fuel consumption LOL!

this would have to 1 of my most hated Qs.... if u are concerned about fuel consumption don't buy a sports car / rotary engine full stop!! - no offence intended.

how can u compare a puny 1.5L hondo engine pumping out 80kW to a race engine pumping out 280kW (250kW - earlier models)?

Pure physics dictates that the more power u make the more fuel & air u require...this is why ferraris only manage 20-25L per 100km.

That said, you can expect an FD best case to get 300-350km / tank. If modded heavily less than 300km is very likely. This is comparable to a modded evo8.

Great~!!!! Brilliant 13btt..2 thumbs up for you~!!! I 100% agree on what you say~!!!

Sedan vs Sport Car???!!! How to compare, buddy~??!!

dude, no offence taken. ANyway, she did ask as FC was 1 of her considerations as she's doin quite a bit of travelling due to the nature of her job.

Anyway, how much does it cost for full tank with current petrol prices? give or take a little.

thanks again.

I've mod a fc with a fuel consumption like around 400~420km per tank of $80 bucks ,
reasonable?

 

[phat7]

coolblue-who are you? Interested to know considering your vast exposure to rotary engines. Maybe you can tune my car.

 

[coolblue]

i'm coolblue la ,

tuning are base on airfuel ratio , not too lean or not too rich ,
if you have stock ecu the air fuel ratio normally not perfect ,
so normally they tune down the fuel because of too rich ,

the best if to do it at dyno , use a wideband sensor a/f ratio meter ,

anyone can do tuning if he has a knollege to tune a ecu base on a/f ratio ,

 

[aiM]

FD3S full tank = 20 Gal, or 76 litre. So, full tank = RM 122.36. Fuel consumption at highway, maintain RPM 3000, 140 km/h without boost is about 30 cent per km. so, you can make 407.87 km per full tank, please note that my engine is 13B-rew earlier model, 255kW. city driving is diffrent, you can calculate around 45 cent per km with a little bit of boost :) if you wanna get better fuel consumption, buy a kancil. RM 20 can stand for a week. please dont compare a sport car with a standard car. Rotary for LIFE~!!

what i would like to know is what experience you have garnered and from where. i run a fully progammable fuel controller and have set a/f at optimum level + safety buffer. Of course this was done on dyno.It is not so easy to tune a/f as on our fd's at least you have to iron out lean mixtures during transition. What kind of a/f readings are you gettng on idle? at boost? what is your inj duty cycle? What kinds of mods have you had done on the fd to achieve said fuel consumption? I am just picking your brains as this will allow other RE members to understand the importance of A/F ratios which is what in many cases causes the engine to knock and we all know under boost knocking=blown engine. Kindly share.

gain from knollege and see exprieces tunes does that ,
cruising low throttle level ( of course if you press extra pedal the boost will come ) ,
they should be arounds 14 to 14.8:1 a/f ratio ,

If you power the car for sure you need more fuel ,
so depends on what boost that you run , different turbo different setup ,

if stock turbine 0.7bar boost are different from big turbo 0.7bar ,
the pressure level are the same but the flow are different ,

if stock turbine should get set around 11.5 ~ 12.0:1 a/f ratio .


you check around www.rx7club.com or www.nopistons.com they have alot of guides for you get your setup done up .

beside that you dont need to really play with the ignition timing , if they preset from factory they should runs well ,

45cents for a KM is really drink fuel la ,

i think you better retune your ecu with a Emanage or a programable Ecu ,

that will save you alot of $$$ ,

hahah... if trafic jam, your car move really slow right? but engine still running, that's why i said 45 cent per km, with max speed of 10 km/h :)

erm, how can u go 400-420 in 80bucks sumore modded? Or is it i misunderstand the currency of our money....is it rm or $?? My car can only go 260-280kmh in rm80 per tank and my car is not modded. Is there something wrong wif my car or something not rite wif ur car?

 

[coolblue]

before fuel hike .. when it was $1.52 per Litre

 

[phat7]

coolblue i'm still baffled with your fc figures. FC3S with what mods? What kind of af value you running? I can get 500 on highway with full tank but thats constant speed of 110-120kmh. What ecu the car running?
